If Alexa's mom paid 1/2 of the $450:
$65
if Alexa's mom paid 1/2 of the remaining price:
$145
Alexa's mom paying 1/2 the $450:
$450 divided by 2 = $225
$225 - $120 = $105
$105 - $40 = $65
Alexa has $65 left to pay
Alexa's mom paying 1/2 of the remaining price after the student discount and Alexa payed $120:
$450 - $120 = $330
$330 - $40 = $290
$290 divided by 2 = $145

Answer:
400 red boxes were sold
Step-by-step explanation:
Step 1: Our output value is 2000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,2000=100%.
Step 4: Similarly, x=40%.
Step 5: This results in a pair of simple equations:
2000=100%
x=40%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
2000/x = 100%/40%
Step 7: Again, the reciprocal of both sides gives
x/2000 = 40%/100%
x=800
Therefore, 40% of 2000 is 800
and to find 50% just divide by 2
